Step-by-Step Instructions
Step 1: Prepare the Tart Crust
In a mixing bowl combine:
- flour
- sugar
- salt
Add the cold butter cubes and use your fingertips or a pastry cutter to mix until the texture resembles coarse crumbs.
Gradually add cold water and mix until the dough forms.
Tip: Avoid overworking the dough to keep the crust tender and flaky.
Wrap the dough and refrigerate for 20 minutes.
Step 2: Pre-Bake the Crust
Preheat oven to 350°F (175°C).
Roll out the chilled dough and place it into a tart pan.
Prick the base with a fork and bake for 15 minutes until lightly golden.
Pro Tip: Pre-baking prevents the crust from becoming soggy once the custard filling is added.
Step 3: Prepare the Buttermilk Filling
In a bowl whisk together:
- sugar
- eggs
- melted butter
Then add:
- buttermilk
- flour
- vanilla extract
- lemon zest
- nutmeg
Mix until smooth and creamy.
The batter will appear slightly thin — this is normal for custard-based tart fillings.
Step 4: Bake the Tart
Pour the filling into the pre-baked crust.
Bake for 30–35 minutes until the center is just set and slightly jiggly.
Tip: The tart will continue to firm up as it cools.
Avoid overbaking, which can cause cracks in custard desserts.
Step 5: Cool and Set
Allow the Classic Buttermilk Tart to cool at room temperature for 45 minutes.
Once cooled, refrigerate for 30 minutes if you prefer a firmer custard texture.
